ABSTRACT:
In vivo-soluble composite particles involving a particle of a polymeric substance such as polylactic acid and the like soluble in a living body, having coated on a surface thereof, a calcium phosphate compound having a Ca/P ratio of about 1.0 to 2.0. The in vivo-soluble composite particles have a highly increased adsorptivity with regard to medicaments, antigens and others and also the in vivo-soluble composite particles can be dissolved or decomposed in the living body without producing a remainder in the body.
